IMPROVEMENT IN GAS-REGULATORS.

Specification forming part of Letters Patent No. 162,704, dated April 27, 1875; application tiled March 13, 1875.

To all whom it may concern:

Be it known that I, DANIEL SLOAN, of the city, county, and State of New York, have invented a certain new and useful Improvement in Gas-Regulators, of which the following is a. specication:

This invention is illustrated in the accom panying drawing, in which- Figure l is a section showing the valve resting on its seat. Fig. 2 is a section, showing the valve raised.

Similar letters indicate corresponding parts.

This invention relates to the class of gasregulators constructed ot' a gravitatnig-valve, which rises and falls under the influence of gas issuing from the valveseat, and serves to regulate the latters flow, and of a set-screw, which serves to regulate the extent of movement of the valve.

My invention consists, mainly, incertain improvements in the valve-seat together with the valve, whereby I promote the uniform flow of the gas, and overcome the impediment arising from impurities in the gas collecting on the valve-seat to a proper working of the valve.

The valve-seat has the form of a truncated cone, while the valve 'is perpendicular, or nearly so, so that a tapering` space is formed between the seat and valve, by means of vwhich the gas is caused to iiow very uniform'- ly, while, if a sediment accumulates on the valve-seat, the valve simply occupies a more elevated position, and its working is not interfered with.

The valve shell or casing is constructed with a cross-bar, through which a tubular setscrew projects downwardly, and to the upper edge of the valve is secured a guide-stem, which projects upwardly into the tubular screw, all of which will be fully hereinafter described.

In the drawing, the letter A designates the shell of my apparatus, provided with an internal and external screw-thread, whereby it may be secured in a gas-pipe or any other place. The internal thread of the shell receives and retains the threaded iiange of a nipple. B, which constitutes the seat of the valve C.

The outline of the seat B is that of a truncated cone, while that of the valve is perpendicular; or, lif seen fit, may be made slightly conical.

By these shapes a tapering space, D, is produced between the inner surface of the valve and the outer surface of the valve-seat. The gas passing through the seat B and striking the valve is caused to retrace its way and pass through the tapering space D, and thence around the lower edge of the valve O to the place of consumption. The gas in its passage through the tapering space D is concentrated, and thus escapes to the place of consumption with a uniform ilow.

It is well known that from impure gases a sediment accumulates on the valve-seat in gasregulators,`and, if permitted to grow, impedes the working of the valve. This is overcome by my invention, in thatas the sediment accumulates ou the conical seat B, the valve only remains in a more elevated position, which, of course, becomes greater as the sediment grows; but which does not in the least interfere with a proper working of the valve.

E designates a set-screw, situated above the valve, and against which the valve C strikes in its up-and-down movement, so that the extent of movement of the valve is regulated. This screw ,E is held in a cross-bar, a, of the valve-shell, is hollow, and receives a guide-stem, b, rising from, and which is soldered or otherwise secured to, the valve. The stem b slides in the hollow or tubular screw D when the valve rises or falls, and by this means the valve is prevented from tipping. In the valve-shell A I form an opening, c, for the purpose of letting out any products ot' condensation of the gas passing through the valve chamber. This opening c receives a plug, Gr, which is held in place by means of a screw-thread, or any other suitable means, so that no gas is allowed to escape by the openmg.

What I claim as new, and desire to secure by Letters Patent, is

The combination, in a gas-regulator, of the valve-casing A, having the conical nipple B, and the cross-bar a, arranged above the same,

the perpendicular valve c arranged over said nipple to create a tapering chamber between the two, and having the guide-stem b projecting upwardly from its upper top, and the tubular set-screw E, projecting down through the said cross-bar ot' the valve-Casin g, all substantially as and for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 9th day of March, 1875.
